Isn't that what volcanoes are?

No, the stuff that comes out of a volcano is magma (which is then called lava when it reaches the surface). It comes from the mantle which is just below the crust.
The core is at the center of the earth and has a composition that is very different from magma. There's an inner and outer core and I assume they're talking about the outer core here since the inner core is thought to be solid.

There are literally mountains ejaculating that shit everywhere, scientists.

Magma vs core material, though.

Reads like an Onion title. 🥵

Well that website is a complete joke so it tracks.

It likely is, actually. Just because it's newly found, doesn't mean it's a new phenomenon.

That is a comforting way to look at it. ✌️

So, like, a Tuesday?

I mean, the metals in the crust have to come from somewhere.
-
I believe that the metals in the crust are primarily
- because the crust froze, before the heavier stuff could all sink down to the bottom, the core, through convection & settling..
- from nickel-iron meteorites, like in Sudbury ( a mining-region of Ontario Canada, which is a roughly-200-km wide crater/impact-site rich in metals )
- because the subducted-crust tends to come back up, through plate-tectonics
- only waaay-down on the list, because the dino-killing impact apparently burst a batch of volcanoes on the opposite-side of the planet, & THEY carried some of the core's metals out onto the surface ( the iridium-rich layer that coats the planet right when the dinosaurs got extinguished couldn't have come from carbonate-meteorite, & that's what testing has declared the dino-killing meteorite to be, therefore the burst of volcanoes which suddenly appeared on the opposite side of the planet must have been the source for all that iridium )

So geology.
I fucking hate that website with a passion.
They post nothing but horseshit for dummies.
edit: I informally petition the moderator(s) to ban that domain
Sounds like there's some interesting new science happening.
I quite like Quanta Magazine, they at least manage to write some pretty good articles on quantum mechanics which are both approachable by layman and accurate.
